To all 'Lc/0m fit may foncer/i:

Be it known that i, ,his-urn ll. niunixi u eitizen of thellniied Sintes. residing*Y in the borough ot' Munhuttnn. in the county o' New York :ind Stute of New York, hure invented eeriuiu new :ind usel'ul improve ments in lleeirimil ppiinnees. oi"l whii'h (he Vfollowingis :1, speeilirnl'iou. reference being hull [herein to the :uroinpnnying drawing.

)ly invention relates to iuiproveinenl'sl in cirruit hr -ukers und luis pzirtieulur referente to :l Circuit breaker :idsipied for use, in conibinution with :i inzifl'neto und distributer :is

used `for igniliug the Cluirges in :in internul (-on'ibustion engine,

In tho urrouilmnyingdruwings i huw illustruled u preferred l'orin otl un' inven tion. I

vFigure i is u rui-tieni eross seetion of suela n ein-uit lu'eulor with the lower poriiuu broken uwuy. Finzi is :i pluu View looking; down ai lin. Lund hint Il :i ero sertiou on the lintl lm o'l Fig'. i slimriun' in dotted outline the outer frzuuo or beni-ing lor the brush wlirh breaks the eirruit.

l: is the outer tube, frznne or suppoi'l ol' the device und is mounted upon the cen'trzil shuft 5. Upon the-upper portion is n ioinited the block (i provided with the slit i' penetrated by the shaft 3 und entered nt the lett by the'bolt 8 so4 that when the shaft is sermred down up'on the slit 7, the bolt 5% is secured in position und n'uiy be adjusted in or out of its bearing by the nul il. ll'vithin the support` lV is mounted the tube i() und lhrough'this tubil penetrates lhe longitudinul tube 1l :is shown. The vtube 10 is p,ro vided with theI coil springl IQ whieh bucks up (he brush or bumper lli. The tube '10 is prorided with :in elongated opening` il so :is to ulhru'jt to shi't from righi lo left pusl the longitudinal lube. 11i. li`roin this4 l it willlie seen tliut :is the oir-ruit breulrer re rolves within the. outer 'ruine 15 shown in dotted outline, in Figli, the tube lOis forced lei'twnrdly looking' ut Fig. u's the. bumper 13 strikes the ruin or elevations .suf'h :is 1G.` As the lube l() lrurels leftwurdly is carries with it the holt 17 secured to the upright 18 rnrryingA the eontnct'point 19, and thu` the ein-,uit is broken between the points g :unl if. The distance ifwouid break is denriuinml by the space Q0 and us previously started this may he adjusted by the nut 9. A Vier the uprigrlit 1,8 lia-s reached the end of ihe pussuue 20, the spark gap formed between ille points S und i9 Cannot Of COUPS@ be iur-reused until the nut or bolt 9 has been zuliusted, Should one, of the earns such as lit-MIU be. :i little higher thun the other, the addition-ul movement given thereby to the bearing il?) taken up by the coil. spring 21, suiiieieni spaiee being allowed :it lfor that purpose` ri`hus it will be seen thatI any unevenness or irregularities in the wearing surrzu'el of the rireuit breaker :ire Cz'ireii for .fhout interfering with the adjusted spark A p. The screw Q3 serves to further se-V in-ul1ited by' the sleeves 24 und 25 und by the wffsi 26. Further i solution is of oui-se, provided by the disk .2?. From this u will be seen that the current lezrves the `Lrouiul from the outer tube or support. 4,

Uf course it will be readily understood that various modifications muy be made Without departing from the spirit of the invention' as set forthvin the claim.
